warning "unexpected middleware set after the adapter. This won't be supported from Faraday 1.0"

Created by: nahzz

I got this issue when using oauth2 v1.4.1, while using /master branch this issue is gone. I think it's because on /master , the way how Faraday is built is different compared to v1.4.1 (see here for master .

Is there a way to get around it for v1.4.1? e.g: pass in some kind of connection_opts when constructing the OAuth2::Client ?
